उत्तर
A thick layer of subcutaneous fat functions as an insulating coat that prevents heat loss from the body and helps to keep the body of the animal warm in colder environments. Moreover, fat also functions as a reserve of food during the periods of scarcity.- Thus, animals of colder regions and fish of cold water have a thicker layer of subcutaneous fat.
